Through-conduit Expanding Gate Valve

BOVE Through-conduit Expanding Gate Valve is a full bore pipe valve, a lifting stem, and a parallel expansion gate that is split seal. It can form a reliable mechanism in both low and high pressure conditions upstream and downstream to close. The design has proven performance in key applications around the world, such as isolation valves for power plants, such as valves in production, high temperature valves for high temperarure wellheads, and pipeline valves in the oil and gas field.

Technical characteristics:

1. Full bore design can effectively eliminate eddy current and pressure drop, and realize pipeline pigging.
2. Bidirectional.
3. The mechanical structure of the expansion gate, regardless of low pressure, high pressure, high temperature to form a reliable seal
4. Seat sealing surface is not in the flow channel, reducing erosion.
5. Single piston effect DBB valve seat.
6. The valve seat and valve stem have a second grease injection sealing device
